Prosecuting, Christopher Rees, said: "Mr Evill set up George Morgan Ltd to divert dishonest health board contracts to himself.
"He created more than one fictitious character, Paul Hewson and David Evans, to correspond with members of health board.
"They are the real names of Bono and the Edge from U2, a band he listens to, used to further his fraud. It's a mark of the blatant and provocative dishonesty."
